IPC: G02F1/35
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To keep intensity of reproduced light constant even if intensity of signal light varies at extremely high speed and to enable light discriminating and reproducing without distortion of a waveform by inputting signal light having the prescribed wavelength and intensity of light obtained through a light amplifying means, a light non-linear type medium, and a wavelength separating means to an optical switch together with clock light. SOLUTION: Signal light inputted to a light amplifier 12 through a light branching device 11 from a signal light input terminal 31 is amplified to the prescribed intensity of light, and inputted to an optical fiber 13. When SC light outputted from the optical fiber 13 is cut out by a band pass optical filter 14, a signal light pulse having a time waveform equal to the input signal light is obtained. A timing extraction circuit 15 extracts a clock signal from signal light branched by the optical branching device 11, gives it to a clock light generator 32, and generates a clock light having a repetition frequency equal to a bit rate of the signal light synchronously with the signal light. This clock light and the signal light outputted from the band pass optical filter 14 and shaped in a waveform to constant intensity of light are inputted to an optical switch 33.

Title: Coordinate switching system for copying control
Inventor: NAKADA YASUYUKI
IPC: G05B19/408
Filed: 1990-02-16
Abstract: PURPOSE:To reduce the calculating load of a controller by changing the time interval for calculation and resetting of a copying coordinate system in accordance with the surface curvature of a subject. CONSTITUTION:A coordinate system switch command means 18 obtains the switching time of a copying coordinate system based on a curvature-coordinate system switching time table, for example, and in accordance with the curvature calculating result of a curvature calculation means 17. When the switching time passed, a command is given to a copying coordinate system setting means 16 via a control command generating part 11 to set a new copying coordinate system. This new copying ordinate system is used until the switching time accordant with the curvature calculated by the means 17 is through. When the switching time passed, the means 18 gives a command to the means 16 via the part 11 to set again a copying coordinate system. Thus the switching time of the copying coordinate system is automatically changed in accordance with the surface curvature of a subject. Therefore the calculating load is reduced for both a position controller 14 and a force controller 15 of a robot 10.
